Anyone with a marketing background will tell you that the most common way to get new referrals is through your website. But the truth is that your website is just the first step. Even if you have a great looking website that clearly indicates who you are and what you can offer your clients, a single visit to your website will not often result in someone contacting you about therapy. The most basic rule of marketing is that people have to come in contact with your "message," six or more times before they really start thinking about your services.
Filling in the form should immediately take potential clients to a Thank You page, which will give them a link to the free product and remind them that they have enrolled to receive your newsletter which will consistently give them important information regarding how they can work on their problems.
Now you've started a conversation with your potential clients, which can last months or even years. Through a bi-weekly or monthly newsletter, using software like Constant Contact (that's what we use for our newsletter), you can soon be an important part of the lives of hundreds or even thousands of people. Some of these people will become your clients. Others may recommend you to their friends. There are many others who you will never hear from, but you will have the satisfaction of knowing that you have helped scores of people you have never met.
You may be thinking that this is somewhat of a "one-sided" conversation, and that is true, but that is the reality of all marketing. You are doing all of the "talking," and your potential clients are doing the "listening." But don't forget that in your reader’s minds, they are making a connection with you. When people wish to engage you in a true dialogue, they will contact you and take advantage of your professional services.
